Specification of Letters Patent. Application iiled April 22| 1907: Serial No. 369,624=j Patented Dec. 31, 1907.

To alllwhom 'it may concern:

Be it known that I, JOHN TRAcEY GAY, a

citizen of the United States, residing at Binghamton, New York, have invented certain new 5 and usefullmprovements in Gage Attachments for' Printing-Presses, of which the fol- 'lowing' is aspeciication. .l

My invention relates to improvements in gage attachments for jiob,- printing presses and has for its'obje'ct to provlde a gage which printing ress, and when so applied may be easily an 'quickly adjusted to accommodate paper.

lhe invention includes the s ecial features of construction hereinafter escribed and invention is illustratedin the accompanying drawing, in whichf- Figure 1 is a plan view of a printing press platen, with the gage in place., Figs. 2, 3 and 4 are detail views. f

Referring by reference characters to this drawing, A, designates the platen of a job rinting ress and B the platen clamps for the ordinary manner. v

C designates ametal bar which has lcli s or plates D and E carried at opposite enge thereof. rllhe clip or plate D 1s referably rigidly secured to the end of the ar, as by riveting, and has a downwardly turned 'end or ilangel d extending at right an les to the body" of the late and designer? to enter between the aten and clamp. The other clip or plate as a similar flange c andit is preferably adjustabl secured to the bar, a convenient form o adjustable connection being set screws e passing through a slot e in thef late. A

To t,A e up er face 'of the bar is secured a plate F whic is wider. thanthe bar so as to provide projecting edges or iianges f and f', the former of whichis provided with notches or recesses as shown. 1

A slide G is constructed to engage these flanges and be capable of movement lengthwiseof the plate F, which slide carries` an larm H extending at right angles to the plate F. The arm H carries a latchbolt I, the end o' which is designed to engage any one of the it to varylng sizes.y of envelops orl sheetsof particularly pointed out in the yappended.

olding t e tympanl sheet tothe platen in i aforesaid notches and hold the slide in any position to which it may have been adjusted, the boltbeing pressed 'towards the notches b a spring K located in a cut-away portion ci] the arm H and encircling the bolt and bearing-against a pint thereon. Y

' The Aend'of the latch bolt is turned at an angle across the face of thearm H by means of which the latch bolt may b e Withdrawn to enable the slide and arm to be adjusted to any desired point when the release of the latch bolt loc svit securely in its adjusted position. 4A slide L rests upon -the upper face of the plate F and has over-turned ledges forming grooves which 'receive the edges of the plate andA this slide lcarries a pgojecting blade-H', which extends over the notched or serrated edge and forms a rest for one edge ofy the card-or sheet of paper to bear against. The 'arm H has an undercut portion or rabbet as shown so that it overlaps the edge of the paper and the blade L also has a projection Z which overlaps the paper and holds it against outward movement. The blade is preferablymade of spring material and has a nob or projection Z designed to engage the notches and hold the slide and blade normally against movement.-

Having thus described my invention, what i I claim is:

1. In -a gage for printing presses, a catch bar having ends fory enga ement with the platen, one of said 'ends eing extensible, teeth arranged on one side of the catch bar, an armdisposed at 7right angles to the said catchy bar, a spring pressed rod connected with said arm engaging the teeth on the catch bar, substantially asdescribed.

2. A gage for the platen of printing presses, comprising a catch bar having ends adapted for connection with/,the platen and having a serrated or notched edge, an arm disposed at right angles thereto, and adjustably connected therewith, a movable slide also mounted upon said catch bar, a projecting blade upon said movable slide extending lengths Wise of the catch bar, and means for locking said slide with its projecting blade upon the catch bar, substantially as described.

In testimony whereof, I affix my signature in presence of two witnesses.
